.To all whom t concern- `Be it known that I, ADDIsoN C. MCEWEN, of Jersey City, in the county of Hudson and State of New Jersey, have'iuvented certain new and useful Improvementsin Dumping -Wagons5 and I do hereby declare thefollowing to be a full, clear, `and exact description of the invenart to which it pertains to make and use it,

Ln A

tion, such as will enable. others skilled in the reference being had to the accompanying draw-y ings, which form part of `this specification.

My invention relates to an improvement in dumping-wagons; and it consists in, rst, the

combination of awindlass mounted upon the seat-platform, an operatingchain which extends therefrom, a shaft journaled upon the v`platform and provided' with a sprocket-wheel anda worm, two operating-chains which are wrapped in opposite directions around the worm, guiding-pulleys, and pivoted body of the wagon, the two chains being fastened to the opposite ends of the.wagon-body, so as-to both dump the body and return it to position;

second, the combination ofthey rear axle, the

knees secured thereto, the plates secured to the knees and to the horizontal timbers which support the body, and the castings secured to the body, and which form the brackets, hinges, orjoints upon which the body turns.y

The object of my invention is to prov-ide a mechanism by means of which the driver sit?y tingupon his seat `can dump the wagon-body and return it to position without having to dismount, either while the wagon is 'in motion or While standing still, and toprovideforlthe wagon body an automatically'- moving tailboard,whih,when the'wagon-body is dumped, leaves its contents f ree to slide out.

Figure 1 is aside elevation of a Wagon to which my invention is applied, the two near wheels being removed. Fig. 2 is a plan View, of the wagonwith the body removed. Fig. 3

is a front view of the-seat-platform and its attachment: Fig. 4is a detached view showing the mechanismby which the body is dumped and returned yto position.'

A represents the rear axle, to which the two knees B are clamped by means of iron straps or other` suitable devices. To the upper ends of these knees B are secured the brackets C, kwhich are formed of two cheek-pieces, which are secured to the knees B at their lower rear ends and tothe horizontaltinbersD,upon'V i "which the wagon-body E is supported. These cheekpieces are 'separatedfrom each otherthe thickness of .the knees B, and in between'the rearvupper ends ofthev cheek-pieces/are Ythe castings F, which are securedA to thennder f u side of the center cross-piece, G, upon the under-side of the bodyvE. These castings'F areI preferably of the shape shown, and 'passing' i through these castings and the cheekpieces U K hinge orjoint upon which the bdyis dumped,

Mounted upon the seat-platform I, and risu ing up ybeside the drivers seat'J, are the two I uprights K. Journaled upon the upper endsy of these uprights is the shaft L, whichvisprofy' vided with a crank, M, upon `one end and ythe pinionN'upon the other.The crank'lM is within easy reach of the driver upon hisseat JJ or while standing upon theplatform I, thus as may be Idesired. The pinion N meshes provided 'with a sprocket-wheel, Q, at its cen- 75 enabling him to dunlop` the wagon-bodyE elther While the wagon is standing still or in motion,

ter and a pawly and ratchet, R, on the' opposite end from the'g'ear O. Around the sprocket` wheel Q upon the shaft P kand the `sprocket- Wheel S on the'shaft T,ijournaled on theunder side of the horizontal timbers D, passes the operating-chainA U,`which receives its motion*y from the windlass Upon the shaft T isY placed vthe worm V, `f around .Which pass the two chains W X in opposite directions. The chain is much shorter than the one X, andpas'ses under the guidingpulley Y upon the *cross-timber Z, and has its rear end fastened to the under side ofthe Wagon-body E. This chain W serves. to draw the wagon-body back into position after having been dumped. Whenthejshaft T isturned'in one directionv for the `purpose of v k dumping the wagon, this chain W'unwinds the front end of the body E to rise, as shown in dotted linesin Fig. 1. When the shaft lTl from the Worm V for the purpose of allowing i i oo is turned in the opposite direction, this chain W is wrapped around the worin V and draws the body E back. into position. The chain .j

rod H' is connected.

is much longer than the one W, and has itsV front end wrappednround the worm V in the opposite direction from the one W, and then passes back over the guiding-pulley A'on the cross-timber B', under the pulley C' upon the rear axle, A, and has its rear end fastened to the screw-threaded rod D', fastened to the under side of the body E. This rod D' is made screw-threaded and provided with a nut upon one end, so that the chain X can be tightened or slackened,according to the amount of movement that it is desired that the body E shall have, and to take up any slack of the chain. When the shaft Tis turnedin one direction, the chain X is wound upon the worm V and a direct downward pull is exerted upon the rear end of the wagonebody E, which is unsupported at this end, for the purpose of 'dumping it, and when the shaft Tis turned in the opposite direction the chain X is unwound from the worm V for the purpose of allowing the chain W to draw the body back into position. While the chain W is being wound upon the worm V the chain X is being unwound therefrom, and thus the body E is held supported between the two chains, so its movement will be controlled from first to last by the windlass.

Secured to each end of the cross-beam E' is a rod, F', upon the end of which is pivoted the rod G', which is connected at its Aupper 4end to thehorizontalrod H,which extendsalongabout parallel with lthe upper edge of the wagonbody E. Upon the wagon-body E is secured a support, l', to the upper end of which the To the rear end of the two rods H', which extend along the upper edges of the wagon-body E, is secured the tailboard J'. Secured to the horizontal rods H are the rods K', which extend downwardly at their rear ends, andv are fastened to the lower ends of -the tail-board J. Vhen the body E begins to dump, the support 1 moves with it, and this support forces the rods H endwise, carrying the tail-board J with them, and causing the rods G to assume the position shown in dotted lines. The endwise movement of the rods H moves the tailboard out of contact with the rear end of the body E, thus leaving room for the 'end of the body to sink downward, while the tai1-board remains vsupported -in the position shown in dotted lines. As the body E returns to position the movement of the support I' causes the rods H' K to have an endwise movement, and thus return the tail-board to position. The tail-board being automatic in its movement, the driver does not have to dismount for the purpose of operating it, as would otherwise be the case.

Having thus described my invention, I claiml. The combination of a windlass located upon the platformfor the drivers seat, the Operating-chain extending therefrom, a shaft provided with a sprocket-wheel, and a worm or drum, the two operating-chains which are wrapped in opposite directions around the worm or drum, the guidingpulleys, and the pivoted wagon-body, substantially as shown.

2. The combination of the rear axle, the knees secured thereto, the cheek-plates secured to the knees and the timbers upon which the body is supported, the castings secured to the under side of the body, and the body, substantially as described. Y

In testimony whereof Iaiix my signature in presence of two witnesses.
